amcorite™ is a proprietary Ferrocement admixture. Developed by Angus W. Macdonald in collaboration with one of the world’s leading cementologists, amcorite has seen years of field testing and refinement. amcorite’s properties: • Can be mixed with standard, affordable, readily-available ingredients: Portland cement, water, and sand. • Creates a thin, extremely strong, Ferrocement structural stucco-like stress-skin. • Increases workability & ease of application over traditional mixes. • Sets quickly; increases strength over time. In comparison to standard Ferrocement mixtures, one of the main advantages of the amcorite/Portland/sand mix is that it is remarkably forgiving: easy to mix, easy to work with & apply, and hard to get wrong – with any type of sand. In fact, amcorite is the “secret sauce” in the am-cor System: many have tried to replicate the am-cor System’s signature disaster-resistant, thin, high strength Ferrocement structural stress-skins, but have failed.
